Error trying to plot pie chart, how to fix?-CodePudding

I was trying out plotting graphs for the first time and tried to do a bit of code where you can enter what parameter you want to graph, and then it graphs it as a pie chart. But when I tried running it, it returns a bunch of errors

import pandas as pd
import matplotlib

plot = input()
plot = str(plot)

df = pd.DataFrame({'Perimeter': [8, 16, 20],
                   'Area': [2, 16, 25]},
                  index=['Square 1', 'Square 2', 'Square 3'])
plot = df.plot.pie(y={plot}, figsize=(5, 5))

The errors are:

C:\Users\KIAN\PycharmProjects\pythonProject\k.py:12: FutureWarning: Passing a set as an indexer is deprecated and will raise in a future version. Use a list instead. plot = df.plot.pie(y={plot}, figsize=(5, 5))

Traceback (most recent call last):

TypeError: Index.name must be a hashable type

Any idea how to fix these or what is causing them?

CodePudding user response：

The variable plot shouldn't be in a set, you don't even need to assign it to a str, input will be already string even if you enter numbers:

plot = input()

df = pd.DataFrame({'Perimeter': [8, 16, 20],
                   'Area': [2, 16, 25]},
                  index=['Square 1', 'Square 2', 'Square 3'])
plot = df.plot.pie(y=plot, figsize=(5, 5))

Output for Area:
